Application filed July 22,

This invention relates to combined typewriting and card-perforatingmachines, and particularly to means whereby, for joint op eration of atypewriter and card-perforator,

the operation of any typewriter-key toprint is translated andtransmitted to the perfo rator as one or more punch-selecting oroperating impulses. An object of the invention is to accomplish this bydevices that are wholly mechanical as distinguished from the heretoforeused means. which involve the use of electromagnets, circuits, contacts,etc. By means of the selected punches, holes are subsequently punched ina card, the location of 5 the holes in the card being descriptive of thecharacters printed by operation of the typewriter-keys.

One advantage resulting from the provi sion and use of the aforesaidwholly mechanical devices is an assurance of positiveness in theoperation of the punch-selecting or punchoperating elements by thetypewriter-keys. With the heretofore used electrical devices, thisassurance has been lacking on account of the lack of absolute certaintyin the operation of said electrical devices. For example, there might bedefective contacts or defective operation thereof. By the operation ofthe typewriter-keys these contacts were actuated to close electricalcircuits for causing the energization of electromagnets which, in turn,actuated the punch-selecting ele ments of the perforator. The failure ofa contact or any other part of the electrical de- 5 vices to functionwould result in improper punching, if, as-is very likely, such failureescaped the immediate notice of the operator. The invention isparticularly useful in a machine of the type shown in my co-pendingapplication, Serial No. 48,723, filed Au ust 7, 1925 (now Patent No.1,683,979, dated eptember 11, 1928). Such a machine, including thewell-known Underwood typewriter and Powers key-punch, both of which aremodi- 15 fied by an illustrative application of the present invention,is herein described and shown. The regular Powers key-punch, which willhereinafter be called the cardperforator, is of the type shown in PatentNo. i0 1, 287 ,706, to W. W. Lasker, dated December CARD-PERFORATINGMACHINE 1926. Serial No. 124,147.

17, 1918. Althou h the machines shown in my aforesaid pen ingapplication and in the present application are in the nature of the workthey perform, only one adaptation of a combined typewriter andcard-perforator, it will be understood that the invention is not limitedto such an adaptation, and may be applied to other combinations oftypewriting and card-perforating mechanisms.

The punches of the perforator herein shown are arranged, as usual, inforty-five parallel columns, each column having twelve punches. \Vhenacard is in position to be punched, each punch in each column registerswith a corresponding hole-space in the card.

' Included in the usual punch-selecting means there is, for each columnof punches, a corresponding column of settable pins. Each pin is inlongitudinal alignment with its punch, and the lower end of the pin isnormally separated from the upper end of the punch by a gap. To select apunch, and thereby make it effective to perforate a holespace in thecard, the settable pin for said punch is depressed and latched in itsdepressed position, so as to close the aforesaid gap.

The usual die-plate, which co-operates with the punches, is movable upand down with the card. During the upward move ment, the selectedpunches, reacting against the pins that arefset against them, perforatethe card, the punches not selected being pushed idly upward by and withthe card.

The usual stripper-plate guides the lower portions of the punches andmoves with the die-plate from which it is. separated by a gap whichreceives the card. During the downward movement of the die and stripperplates, which immediately follows their upward movement, the card isstripped from the punches. Each punch has at its upper end a shoulder,and, while the card is being stripped from the punches, the shoulders ofsaid punches react against a fixed plate, which also guides the upperportions of'the punches.

To depress the pins, there is provided for each pin-position in a columnthe usual pinsetting plunger. In the present case there are twelvesuch-pin-setting plungers, and they are arranged in a column whichcoincides with the arrangement of a column of pins. The column ofpin-setting plungers is mounted in a movable carriage, by means of whichthe column of plungers may be moved to register with any column of pins.When they so register, the corresponding pins and plungers are inlongitudinal alignment, and their adjacent ends are separated by a smallclearance to assure free movement of the carriage.

In the regular card-perforator the plungers are actuated to set pins, bykey-controlled means, which are part of the regular perforator, andwhich also actuate an escapement-mechanism, whereby theperforatorcarriage, under the pull of a spring-motor, is automaticallyshifted, so that the column of plungers will register with column ofpins.

The purpose of combining the perforator with the typewriter is that theoperation of the typewriter-keys to print shall also set the pins of theperforator, so that the holes corresponding to the characters typed maybe punched in a record-card. These perforated record-cards are used inthe well-known processes of mechanical accounting. In the adaptation ofthe combined typewriter and card-perforator herein shown, the typing isdone on the record-card, and produces a heading on said card which isdescriptive of the holes to be punched in the card. To insure that thepositions of the typewriter and cardperforator carriages shall always bein correct relation to one another, the carriages are positively coupledtogether, as shown in my.

aforesaid co-pending application, Serial No. 48,723.

After the heading has been typed, the card is removed from thetypewriter and presented against feed-rolls of the perforator. Upondepressing the usual key, a machine-cycle of the perforator is effected,which causes the feed-rolls to draw the card into punching position, andalso causes the card to be punched according to the pins that were setby the operation of the typewriter-keys. After the perforating cycle;the perforatorpins that were set are automatically restored during thereturn ,of the carriages to their starting positions, and the machine isready to type and punch another card.

Some alphabetical characters and other symbols mustnecessarily berepresented by more than one hole in a card-column, because acard-column has only twelve hole-positions, which are exceeded in numberby the total number of characters printed. In carrying out that part ofthe invention, which is directed toward means whereby the operation ofthe typewriter-keys may actuate the pinsetting plungers, there areprovided first of all mechanical translating means, whereby thesucceeding only the pin-setting plungers corresponding to any operatedtype-key are caused to be actuated. The typewriter-keys, as usual, aremounted on key-levers.

A selection of the pin-setting plungers to be actuated is bestaccomplished by means which include a number of what may be calledselector-members, which have edges that extend transversely of andunderlie some suitable part of the typewriter type-actions. In thepresent case there are twelve such selector-members, one for eachpin-setting plunger, and they underlie the typewriter keylevers. Amaterial edge that overlies and extends transversely of the edges of theselector-members will engage and displace only certain ones of theselector-members, if a suitable portion of and below the edge of eachselector-member that is not to be engaged by said material edge is cutaway. For example, the letter M is represented in the card by theeleventh and twelfth hole-positions, and, therefore, when typing theletter M, .the eleventh and twelfth selector-members must be actuated.In this case each of the other selector-members has its edge cut awaywhere the aforesaid material edge related to the M-key would otherwiseengage it, the cutaway portion forming a slot that clears thematerial'edge as it moves to displace the active selector-members. Eachkey has its own aforesaid material edge, which is preferably embodied inan interponent between the keylever of said key and the edges of theselectormembers.

In this manner the operation of a key is translatedinto the displacementof one or more selector-members, each of which corresponds to apin-setting plunger. The invention further provides means whereby saiddisplacement is positively transmitted to said plungers, which are thusoperated to set the corresponding pins. It is a feature of the inventionthat no part of said transmitting means is carried by theperforator-carriage, and there is therefore no tendency to impede thefree movement of said carriage. Operating contact with the plungers istherefore best made by means of bars, the lower edges of which areadjacent those portions of the plungers with which such operatingcontact is made. In order that the plungers may be operated irrespectiveof the position of .the carriage, said lower edges of the bars are neeessarily parallel to and co-extensive with the paths described by theaforesaid portions of the plungers as the perforator-carriage moves fromcolumn to column.

In the present embodiment of the invention the perforator is locatedbehind the typewriter with the body of the perforator higher than thetypewriter. Operating extensions of the plunger-actuating bars towardthe typewriter" are effected by making each of said bars an upper chordof a light frame,

the vertical sides of said frame extending along and running close tothe .outer vertical sides of the perforator-frame. Each of the two sidesis guided near its upper end for the up-and-down movement of the framethat is necessary to actuate the plungers. This up-and-down movement ofeach frame is derived from the up-and-down movement of .thecorresponding selector-member under the typewriter.

To transmit the up-and-down movment of the selector-members to theplunger-actuating frames, there is provided for each frame andcorresponding selector-member a connecting rock-shaft having at each endan.

arm, both arms extending in substantially the same direction. The endsof each arm are connected respectively to the plungeractuating frame andthe selector-member. The shafts areof evenly varying lengths, so thatthe shafts with their arms may be nested one within the other. In thenested arrangement the shafts lie in a. horizontal plane that ispreferably below the typewriter and the body of the card-perforator.

The selector-members are preferably in the form of flat light plates andare mounted in guides for an edgewise up-and-down movement. The upperedges of the plates coact with transverse edges of the aforementionedinterponents that are actuated by operation of the type-actions, andsaid upper edges are of a length sufficient to encompass all of theedges of said interponents. The plane in which the aforementionedconnecting rockshafts lie coincides approximately with the lower edgesofthe selector-member plates, which are of sufficient vertical depth toallow the plates to be properly guided. The two sides of eachplunger-actuating frame are joined by a chord below the body of theper-i forator. A. midway portion ofeach chord is extended edgewise anddownwardly in the form of a panel, so that the lower edge there- ,of maybe connected to one of the aforesaid connecting rock-shafts. Apin-and-slot connection joins each panel near its lower edge to an armof said connecting rock-shaft, the

other arm of which is operatively joined to the correspondingselector-member plate by an abutting connection, the end of thelastmentioned arm simply abutting against the lower edge of the plate.The interponents between the type-actions and the selectormember edgesare guided in a fixture mounted on a platform that supports thetypewriter, the interponents projecting through a'hole in said platform,so that the lower edges of said interponents are below the bottom of theplatform, which is separated from a lower platform by an interveningspace in which the selector-member plates are arranged side by side. Theselectormember plates are supported and guided in a fixture mounted uponthe lower platform and project through an opening in said platform, sothat the lower edges of said plates are below the bottom surface of saidlower 1platform. Against this lower surface, the

arings for the connecting rock-shafts are fastened, the shafts alsobeing below said surface. Both platforms extend from theperforator-supporting frame. A spring is applied to each interponent tohold it in normal position. Suitable springs are also applied to eachpunch-selecting frame to counterbalance its weight and also the weightof the parts reacting upon said frame. The punchselecting frame springsalsohold the frames and said parts in their normal positions.

A further object of the invention is to provide a simple key-controlledpower-drive, so that the fingers of the operator may be substantiallyrelieved not only of the work required to operate the type-actions toprint, but also of the extra work involved in simultaneously actuatingthe pin-setting pliungers by the means herein outlined. A feature ofsaid power-drive i that it may be applied to the typewriter with aminimum number of changes in said typewriter. To this end, there isprovided a bar extending transversely of and below the key-levers. Thisbar is given a continuously and rapidly reciprocating edgewise movementof suflicient extent tooperate the key-levers in a full stroke. Thisreciprocating movement is best derived by means of the well-knowneccentric and coacting slotted arm device, the slotted arm beingfastened to a rock-shaft to which the bar is attached by arms. Anelectric motor drives the eccentric to which it is geared for a suitablespeed. Each key-lever has pivot-- ally attached to it a swingablemember, a portion of which may, by swinging the member, be interjectedinto the path of said reciprocating bar, with a consequent displacementand operation of the typewriter key-lever to print. 'F or eachtypewriter key-lever there is provided an auxiliary key-lever wherebythe displacement of the corresponding swing able member into the I ingbar maybe selectively effected. The keys .of these auxiliary key-leversconstitute an auxiliary keyboard, and said auxiliary keylevers are sodisposed that the auxiliary keyboard is just above the regulartypewritem keyboard with sufficient space between the two keyboards topermit free operation of the auxiliary key-levers. The interjectableportions of the aforesaid swingable members can only be fullyinterjected into the path of the reciprocating bar when the bar is atthe extremity of its upward movement. In order that an auxiliarykey-lever may be operated path of the reciprocatin an interval betweensuch extremities, a

yieldable operating connection is provided between each auxiliarykey-lever and the swingable member of the corresponding typewriterkey-lever. v

Figure 7 is a perspective view, showing the power-driven means foractuating the typeactions.

As shown in Figure 1, a typewriter is combined with a card-perforatorfor joint operation in which a record-card 10, placed around a platen 11of the typewriter, may have a heading printed near its upper edge byoperating the usual typewriter-key-levers 12, which swing about afulcrum-rod 15 to actuate bell-cranks 16. Said bell-cranks 16, inswinging about a fulcrum 17, operate typebars 18 to print against saidcard through an inked ribbon, not shown. Every time a typebar 18 prints,the usual Underwood escapemen-mechanism, generally indicated by the.

number 19, is actuated by said type-bar to cause .a carriage 20, inwhich the platen 11 is mounted, to move a letter-feeding step. Theletter-feeding steps are impelled by the usual Underwoodcarriage-spring-motor, not shown. The key-levers 12 have mounted thereonthe usual numeral-keys 13 and alpha I bet-keys 14. In the jointoperation of a typewriter and card-perforator, every time a character istyped, certain elements in the perforator are set that subsequentlycause perforations corresponding to the character typed to be punched inthe card.

The record-card is divided into columns, each having twelve hole-spaces.Since there are approximately forty-two keys in the typewriter,combinations of several holespaces in a column must be used to represent-til the card is free.

some of the characters printed. The recordcard has forty-five columns ofsuch holespaces, and for each hole-space there is a corresponding punch21 in the perforator, the punches being arranged in columns of twelveeach. A side view of one of the columns of punches is shown in Figure 1Coa'cting with said punches in the punching of a card, is a die-plate 22having a hole for each punch. The die-plate is included in Whatconstitutes a card-frame 23." Said card-frame also includes astripper-plate 24, which is separated from the die-plate by a gap, whichmay receive the card'to he punched. After the heading has been typedupon the card, it is removed from the typewriter by rotating the platenin the usual line-spacing direction un- When the card isfree of theplaten, it is slid rearwardly over tablesurfaces 25 and26, that are partof the typewriter-carriage, and into guides 27, one of which is shown inFigure 1. By means of these guides and a platform 28, on whichsaid'guides are mounted, the card is directed toward the first ofseveral pairs of feed-rolls 29, againstwhich the leading edge of thecard is presented. The usual" starting key, not shown, is then pressedto initiate an operating cycle of the card-perforator, and, during thiscycle, the feed-rolls 29 draw the card into punching position against amovable stop 30. The feeding of the card into punching position occursduring the first part of said cycle. During the last part of said cyclethe frame 23, with the card in the aforesaid gap, is moved upwardly toeffect punching of the card. In order that a punch may penetrate andperforate a card,'the lower end of a 'pin 35 when interposed in the pathof said punch, opposes said punch as it moves upwardly with the card.The pin 35 is interposed and latched in its depressed position. There isone of said pins for each punch and they are arranged in columns oftwelve each. To latch the pins in their depressed position, there isprovided, for each column of pins, a spring-pressed latch-plate 36.During the aforesaid cycle of the perforator, a main shaft 31 of theperforator makes one complete revolution, and from this revolution theupward movement of the card-frame 23 is derived by means of a cam 32fastened to said shaft and a rocker-frame 33, which constitutes theconnecting means between said cam 32 and the card-frame 23. Punches forwhich no pins are set are moved idly upwardly by and with the card.Immediately after the upward movement. of the. frame 23 with the card,the frame and card are retracted by the continued rotation of the camduring the remainder of a cycle. During this retraction, the card isstripped from the punches, which have penetrated it, and, during thisstripping action, the shoulders of the punches react against a fixedplate 37 which also guides the upper card into punching position. At thebeginning of said cycle, the card-stop 30 is withdrawn for a timelongenough to permit the passage of the punched card. The punched cardis deposited in a receptacle 49 Punchings from the card drop into apocket 38 attached to the under side of a perforatorplatform 51. Tofacilitatethe removal of said punchings, the pocket is provided with ahinged flap 39.

Thus it will be seen that the selection of the unches which are toperforate the card is e ected by depressing and latching 'the pins 35corresponding to said punches. The pins 35 are depressed in one columnat a time. To depress the pins, there is provid-' ed a column ofpunch-indexing lungers 40 arranged to colncide with a co umn of pins. Inorder that the pin-setting plungers 40 may be moved to register with anycolumn of pins 35,, the are mounted in a carriage, enerally indicated bythe number 41. Said carriage is supported and guided by means of rails42 and rolls When a character is typed upon a card, the punch-indexingcarriage 41 must be in a position corresponding to the typing po'sltlonon the card. In order that the positions of the typewriter-carriage 20and the punchindexing carriage 41 shall always be in proper relation toeach other, said carriages are coupled by means of a rack 44 supportedon brackets 45 on the perforator-carriage, and a rack 46 supported onbrackets '47 on the typewriter-carriage. A .pinion 48 constitutes thecoupling means between 'said racks, and is mounted on a column 49supported by the platform 28. By means .of said racks and pinion the twocarriagesalways move in unison.

To secure the proper relative positions I of the type-writer and thecard-perforator,

so that they may be coupled by said racks and pinion, the typewriter issupported upon a platform 50, which in turn is supported by the platform.51 of a perforatorframe, generally' indicated by the number 52. A lowerplatform 53 is provided to support some of the connectlng devices between the typewriter-and the perforator, said connecting devices forminga part of the invention to be explained. Said lower platform 53 isseparated fromthe platform' 50 by front and rear studs 54. Spacers 55establish a proper level for the platform '50. The lower platform 53extends rearwardly as far as the rear edge of the platform 51, fromwhich it is separated at the rear by plunger.

a spacer 56. Suitable bolts 57 secure the usual typewriter-keyboard.Said code is,

also indicated in Figure 6. In order that the operation of any key-lever12 -may be translated for a pro er selection of the correspondingpunch-indexing plunger or plungers 40 to be actuated, there is providedbelow the typewriter a number of selector-members 58, one for eachindexing Each of these selector-members has a horizontal edge 59 thatextends transversely of the key-levers 12. Since each of theseselector-members 58 corresponds to an indexing plunger 40, adisplacement of a selector-member is equivalent to displacing a plunger,if said displacement is transmitted to sald plunger. To selectivelydisplace the selector-members58 by the operation of any key-lever 12, aninterponent 60 is provided between each key-lever and theselector-members. A lower edge 61 of said interponent extendstransversely of and encompasses the upper edges of all of theselector-members. Each interponent 60, disposed as shown, when displacedby the operation of'its related key-lever, will displace only theselector-members corresponding to said key-lever, if the aforesaid edges59 of the other selector-members are cut away adjacent the edge 61 ofsaid displaced interponent. Each selector-member, therefore, has anumber of slots 65, which clear the edges of all the interponents, withthe exception that where an interponent, throughits key-lever,

.is intended to actuate a selector-member,

there is no slot or cutting away of the upin Figure 1, the interponentsare in the form of an inverted T, and are guided in a fixture 62 that issupported by the platform 50. A sprin ponent, to ho d it in its normalposition in whicha bent-over tab 64, at the upper end of theinterponent, bears against the lower edge of the key-lever 12. One endof said spring 63 is attached to -the interponent, and the other 'end isattached to a suitableprojection 65" from the fixture 62. As-shown 1nFigure 1, the lower edges 61 of the inter{ ponents are below theplatform 50, which nents an their supporting fixture 62. The

selector-members 58 are in the form of light A 63 is applied to eachinter- 126 has. an'opening 69- that clears the interpo rolls 66 pivotedon rods 66 in fixtures 67 and 68, secured to the lower platform 53, seeFigure 5. An opening 69? in said lower platform 53 clears theselector-members, the lower edges 7 O of which are below the platform53. On the under side of said platform 53, part of the operatingextensions from said selector-members to the punch-indexing plungers maybe conveniently disposed, as will/be explained.

In order that operating contact may be had with the punch-indexingplungers in any position of the punch-indexing carriage 41, there isprovided for each plunger 40 a bar 72. The lower edge'of said bar 72 isaligned to the upper end of its corresponding plungor 40, said upper endbeing in the form of a bent-over tab 73 of sufiicient width to insureoperating alignment at all times with the bar 72. The lower edge of eachbar is parallel to, and at least co-extensive with, the path describedby the upper ends of the traveling plungers.

The plungers 4O perform the same function as the usual plungers of theregular perforator. In the resent invention they are actuated by the bar7 2, and each plunger has a retracting spring 74, which holds theplunger in its normal position, in which a shoulder 75 reacts against acomposite plunger-spacing plate 76 mounted on the carriage 41, and madeof separable members, to facilitate the insertion of the plungers inassemhling.

The lower ends of the plungers are guided by a slotted plate 71, and arepreferably free to lag behind the movement of the punchindexingcarriage, so that there shall be no tendency, on account of a relativelyslow retraction of the plunger, to impede the movement of the carriage.For thisreason the guide-slots of the plate are extended sufficientlytoward the left to permit said lagging of the plunger ends, and theplunger-springs 74 are, inclined sufficiently to yieldably hold saidplunger ends in normal position against the right ends of theguide-slots, as shown in Figure 5. Each of the bars 72 forms an upperchordof a frame, generally indicated by the number 77. Each of saidframes 77 constitutes a stationary train of operating connectionsbetween a plunger and a selector member 58. For this purpose, the sides79 of the frames are directeddownwardly and along the outer side frames80 of the main 1 body of the perforator. A suitable opening 81 isprovided in the perforator-platform 51, to clear the sides 79 of saidframes. Below the platform 51 the sides 79 of each frame are joined by achord 82. A midway portion of each chord 82 extends downwardly and formsa panel 83. A lower portion 84 of said panel 83, like the lower edge ofthe selector-member 58, is below the lower platform 53, so as to beconveniently adjacent the connecting means between the frames 77 and theselector-members 58. Said connecting means are preferably a series ofshafts 85, one for each frame and corresponding selector-member. Theshafts are of varying lengths, the shorter one connecting the innerframe with the inner selector-member, as shown in Figure 4, and thelonger shaft connectingthe outer frame with the outer selector-member.By thus progressively varying the lengths of the shafts. they. withtheir connecting arms 89 and 92 to the frames and selector-members, maybe nested one within the other, as indicated in Figure 4. For supportingthe shafts, there is secured to the under surface of the platform 53 abracket 86. Bearing holes for the shafts are in a series of bent-overtabs 87 formed at either end of said bracket 86. The end of each arm 89is in the form of a bent-over tab- 90 that abutsagainst the lower edgeof the corresponding selector-member. Connection between the arm 92 atthe other end of the shaft and its corresponding-frame, is made by meansof a pin-and-slot connection 93. It will be seen from Figure 4 that anedgewise vertical displacement of a selector-member 58, caused byoperating a type-action. causes an edgewise vertical displacement of theframe 77, and consequently of the bar 72, the displacement of the bar 72being effective to actuate a corresponding punchindexing plunger. Theframes 77 are guided at each side at their upper portions by slottedbrackets 78, which are attached to the pcrforator side frames 80. Thelower portions of the frames are guided by means of slotted plates'81fastened to the lower platform 53. A spring 88 on each side of eachframe 77 keeps the frame in its normal position, in which stop-pins 91,driven into the sides 79 of each frame. engage the brackets 78. One endof each of said springs 88 is anchored to the corresponding bracket 7 8,and the other ends of said springs are attached to the adjacent sides 79of the frames. The springs 88 also counterbalance the weight oftheframes 77 and the train of mechanism between each frame and thelevers 12. All of the parts, constituting a mechanical train between thelevers 12 of the typewriter and the punch-indexing plungers 40 of theperforator, are to be madeas light as possible, so that resistanceagainst their operating displacement is reduced to a minimum. and forthis reason said parts should be limited in size and number as much aspossible without sacrificing the rigidity necessary for their positiveoperation, which constitutes a feature OfthlS invention. For example,the selector-members 58 and the lower panels 83 may have their interior.portions cut out, as indicated by openings 94 and 94, respectively (seeFigure 4):

In the preferred form of the invention,

.from said bar.

power-driven means to operate the type.- actions are provided to relievethe fingers of the operator, not only of the work necessary to operatethe type-actions to print, but also of the work involved in operatingthe punchindexing plungers 40 by the means herein described. As a sourcefrom which operating impulses for said type-actions may be derived,there is provided a rapidly-reciprocating bar 95, which extendstransversely of and under the key-levers 12. The reciprocating movementof said bar 95 is derived by means of an eccentric 96, which coacts witha slotted arm 97 fastened to a rock-shaft 98, to which the bar 95 issecured by means of arms 99. The eccentric 96 is formed upon the side ofa gear 100, which meshes with a driving gear 101 fastened to a shaft 102of a driving motor 103. To support the gear 100 for rotation, there isprovided abracket 93* mounted upon the platform 50, which also supportsthe driving motor 103. Said gear is preferably made to rotate upon asuitable stud secured in said bracket 93. If said gear 100 is journaledin a bearing hole in said bracket, said bearing hole must be ofsuflicient length to furnish proper bearing for the journal, which, inthat case, is part of said gear. The rock-shaft 98 has its bearings inside frames 109 of the typewriter.

As an operating connection between the reciprocating bar 95 and eachkey-lever 12, there is pivotally attached to each key-lever a swingablemember 104, see Figure 7. Said swingable member 104 has a lowerhookshaped portion 106, which, by swinging the member, may engage thebar 95. Said hookshaped portion is normally disengaged To effect theselective engagement of the hook-shaped portion, there is provided foreach key-lever 12 an auxili- .ary lever 107. Said auxiliary levers arepivoted on a common fulcrum-rod 108, which is supported by and betweenthe side frames 109 of the typewriter. A stop-rod 110 determines thenormal positions of said levers, and a stop-rod 111 determines theextent to which said levers may be rotated. Each of said auxiliarylevers is yieldably held in said normal position by means of a spring112 secured to a bar 113 that is supported by and between the typewriterside frames 109. Suitable bracing means, not shown, may be providedtosupport the rods 110, 111 and the bar 113 against sagging. Thespring-bar 113 may be similarly braced by means, not shown. The outerarms of the levers 107 are formed so that keys 105, mounted on the endsof said outer arms, constitute an aux iliary keyboard above the regulartypewriterkeyboard, said auxiliary keyboard being substantially aduplicate of said regular keyboard. The inner arms 115 of said levers107 are substantially uniform.

of the lever 117 engages the edge of the swingable member 104, and saidtab and said edge are drawn together by a spring 119, which normally hasthe effect of making substantially one lever of the swingable member 104and the lever 117. The upper arm of each lever 117 has a suitably curvedportion 120, which lies in the path of the end of the arm 115, of theauxiliary lever. When said auxiliary lever is rocked, the curved portion120is displaced by the end of the arm 115, and the-hook-shaped portion106 is consequently caused to be interjected into the path of thereciprocating bar 95. It is for the reason that the hook-shaped portioncan only be interjected when the bar 95 is at the extremity of itsupward movement, that the aforesaid yieldable device, including thelever 117 and spring 119, is provided, and said yieldable device becomeseffective if the auxiliary lever is actuated in the interval betweensuch extremities. If the upper edge of the bar moves below the normallevel of the ends of the swingable members 104, said lower ends or upperedge should be beveled, so that a member 104 may ride over said bar ifits hook-shaped portion 106 is in the path of said bar at the beginningof its upward movement. Figure 2 shows an auxiliary lever 107 operated,and the corresponding hook-shaped portion 106 engaging the bar 95 at theextremity of the upward movement of said bar. At the end of the ensuingdownward movemet of said bar the relative positions of the involvedparts are as shown in Figure 3.

A spring 116 is attached to each lever 117 and keeps said lever with itsrelated swingable member 104 in normal position,in which the lever 117-stops against a pin 114, proj ecting from the side of the key-lever 12.It will be seen that the power-driven means herein described foroperating the type-actions may be easily applied to the typewriter witha minimum of change. It will be understood, however, that the inventionmay be used with any other form of power-drive for operating thetype-actions of the typewriter The power-drive herein described ispreferred on account of its simple and novel features, which make iteconomical to manufacture, install and maintain. It will also beunderstood that a power-drive for the type-actions may be dispensedwith, in which print and actuate the pin-setting plungers by means ofthe regular typewriter-keys 13 and 14.

case the type-actions would be operated to v A blank card is adjusted tothe platen 11, the carriage shifted to the letter-space position for thefirst character to be typed, the motor 103 started to continuouslyvibrate the bail 95, and a key 105 is depressed to the Figure 2 positionto swing the member 104 that is pendent from the'associated lever 12into engagement with the bail, to be drawn downwardly to depress saidlever, to throw its type-bar to typing position. The depression of thelever 12 engages the tab 64 to depress the interponent 60, which, inturn, depresses one or more selector-members 58 not provided withclearance slots 65. The depressed selector or selectors 58 engage theend or ends 90 of crank-arms 89 to rock shafts 85, to vibrate crank-arms92 having pivoted connections to the frames 77, to pull the cross-bars72 thereof downwardly to depress punch-indexing plungers 40 whichdepress punch-setting pins 35 that become automatically locked in theirdepressedpositions. The release of the key 105 eifects a letter-spacemovement of carriage 1 20 and a pin-space movement of the carriage 41and the several parts of the mechanical train of connections actuated bythe key 105 are restored by springs 88.

After typing the last character on the card, a series of punch-settingpins 35 remain locked and in punch-intercepting positions,

so that when the typed card is removed from the platen, the card is fedto the rolls 29 and into the card-punching position under the punches21, the depression of a trip-key, shown and described in my aforesaidpending application, operates to cycle the shaft 31 and the cam 32 toraise the card against the punches 21, and those punches that areintercepted by the indexed pins 35 are forced through the card to leaveperforations, when the card is withdrawn, that are descriptive of theitems previously typed on the card. The depression of the well-known.carriage-re turn key, not shown, restores the typewritercarriage,restores the pin-indexing carriage, and automatically releases theindexed pins 35 in a well-known manner.

It will be understood that the punch-indexing mechanism with itscounterbalanced trains of connections to the levers 12 may be operatedby the manual manipulation of the usual character-keys 13, and that whenthe power-driven mechanism is employed, the

: keys 105 become the operatingkeys, and the levers 12 become type-bardrivlng levers and not key-levers.
